Getting Started Guide

Before You Get Started

The section below provides getting started tips on common elements in the browser

interface and features that can affect how you see data in the monitoring dashboards.

Working in a Current or a Diagnostic Time Range

This getting started tip helps you understand whether you are working in a real time

range or a diagnostic time range and how to switch from one to the other.

Note Some pages do not take a time range input and so do not display a time range.

By default, the time range at the top of a dashboard is in real time. When the time range

is in real time, the icon and the word Now are shown in the time range display.

Figure 1

Hovering over the real time range icon displays a message that identifies the time range

as real and informs you how to freeze the time range.

Figure 2

If you drill down on an alarm, vFoglight disconnects from real time and enters a

diagnostic time range. The diagnostic time range spans the same length of time as the

current time range did prior to the drill down.

Within a diagnostic time range, vFoglight typically sets three-quarters of this span to

occur prior to the alarm being fired and one-quarter to occur after. For example, if the

current time range spans four hours, when you drill down on an alarm, the diagnostic

time range also covers a four-hour interval, from three hours prior to when the alarm

fired to one hour after it fired (as shown in the image below).
